The budget needed is significantly influenced by the methods selected and the scope of the question. Our costs in the past have ranged from ca. 20.000€ for a rapid evidence assessment to ca 75.000€ for a systematic review; the time required after scoping from 5 to 15 months. The cost of the scoping phase is fixed at 2.000 €.
In order to help to define a budget, Eklipse Method Expert Group (MEG) created a tool called MAGICKS (Method Application and Guidance In Conducting Knowledge Syntheses), to inform on the process of identifying which methods meet your synthesis needs, as well as clarifying your synthesis parameters. More information about this application can be found here.
